I'm actually having this same issue but with the 6i3syh and at a much large time period. it happens about once a day when I've had it staged. I've upgraded all the drivers and the bios so ill see how that goes. Nothing stand out to me in event viewer. just see the standard unexpected shutdown event.

Does Windows show the "shutting down Windows" screen for a few seconds and then reboot?

Or is it an instant reboot with no windows shutdown screen?

Instant reboot, without any notification.

We have created an image which we deploy via WDS. the same image on the same NUCs but different problems.

It seems that there is no actual correlation between 3rd party hardware/OS. those NUCs are just not working.
